Fair enough.. I thought it was easy to follow what I was saying but I see what you're saying. In the cases I was talking about, 'increasing AoA' meant that if it was positive, it was getting more positive and if it was negative, it was getting more negative - in both cases, the angle is getting bigger relative to itself. Since I was talking about a normal airplane that is right-side-up, I assumed wing lift to be acting upwards away from the earth and tailplane lift acting downwards towards the earth.
